IPv6 is becoming a big topic at the moment.
We expect IPv4 addresses to run out this year. This isn’t so bad as we expect ISPs will start selling addresses to each other which will even out supplies for a few years.
But the future is IPv6. At ProVu we have had our network IPv6 activated for about 5 years. This has given us lots of experience.
We are also pushing all of our suppliers to update us on their IPv6 status. Ideally, all phones would support IPv4 and IPv6 dual stacked at same time.
We’ll update you as time goes on.
